HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

7-Bromo-5-chlorobenzofuran is a halogenated benzofuran scaffold featuring complementary bromo and chloro substituents at electronically distinct positions. This configuration enables selective cross-coupling reactions under palladium catalysis, facilitating the construction of complex heteroaromatic architectures in medicinal chemistry and materials science applications.

Application

7-Bromo-5-chlorobenzofuran serves as a versatile building block in the synthesis of functionalized heterocycles and pharmaceutical intermediates. The ortho-halogenated scaffold enables palladium-catalyzed cross-coupling reactions with high regioselectivity, facilitating the construction of complex biaryl systems. Its bench-stable nature and compatibility with diverse reaction conditions make it ideal for medicinal chemistry campaigns requiring precise substitution patterns on benzofuran cores.
